Using playlists is something that most people who play music from digital sources are accustomed to, and because of this, the UMP offers a flexible and relatively transparent playlist function. Although Playlists can be used for Images or Videos, the function was implemented mainly for Music files. To create a playlist, simply highlight an audio item in the Music Menu or one of its submenus and press the color button on the remote control (UMP-R-1XX) indicated in the Button Bar for the Enqueue this Music in Playlist function.
When a new playlist is created, it uses the current date and time as a title for ease of chronological archiving and to ensure that a unique name is used. To maximize compatibility, M3U playlists are generated by default, and are the recommended type. The common PLS playlist format is also supported, but with an impact on the responsiveness of the device when dealing with many items in a single list. It is recommended that a playlist does not exceed 500 – 1000 items, though there is no theoretical limitation.
When opening a directory in the Music Menu or one of its submenus, an entry is listed before the files themselves called ‘Random playlist’. This function enabled recursive random playback of all items in the current folder and its subfolders, but does not save the generated playlist. Similarly, autoplay uses the playlist function for most types of media, though the playlist itself is not saved in an accessible way.
To manage playlists, open the Music Menu in the OSD and navigate to Playlists. Here you can see an overview of the manually created playlists. In the Button Bar you will see a number of functions, including but not necessarily limited to:
- Play: Plays the currently selected playlist in its original order
- Random Play all items: Plays all items in the selected playlist in random order
Additionally, you can perform an Alternate Select on a playlist item, and choose Browse Playlist. This allows you view all tracks in the playlist and play or delete them. Note that deleting an item from a playlist will NOT delete the file, and the deletion of a file will ALWAYS request confirmation.
To enqueue an entire directory to a playlist, Alternate Select it and choose Enqueue this Music in Playlist.
If you edit a playlist manually, do not add blank lines, they can cause the OSD to refuse to load it.
